Iqela lezendalo likhuphe ikhadi lalo lengxelo ngolwesiThathu ngendlela iinkampani ezihamba ngenqanawa ezisebenza emanzini aseMelika eziqhuba kakuhle ngayo ukunciphisa ungcoliseko, kwaye akukho namnye ofumene ibakala elipheleleyo "A."
Abahlobo boMhlaba bafumene i-10 leendlela eziphambili zokuhamba ngenqanawa, kubandakanya amagama amakhulu kwishishini, njengeCarnival Cruise Lines. ICarnival ifumene "D-minus."
Ingxelo ikhuphe ibakala eliphezulu - "B" - kwi-Holland America Line. I-Norwegian Cruise Lines kunye ne-Princess Cruise nazo zifumene amanqaku afanelekileyo, ngamnye wafumana "i-B-minus."
Awona mabanga aphantsi — “Fs” — aye kwiDisney Cruise Line kunye neRoyal Caribbean International. IiCruise zosaziwayo kunye neSilversea Cruise nazo zafumana amanqaku asezantsi.
ICunard Cruise Line kunye neRegent Seven Seas Cruise zifumene malunga namabakala aphakathi.
Ngokwesiqhelo, abakhweli beenqanawa zokuhamba ngenqanawa batsalwa kuhambo lokuhamba ngenqanawa ngemifanekiso yamanzi acwengileyo kunye nezithembiso zeendawo ezingonakaliswanga kunye nezilwanyana zasendle ezininzi, kodwa aba bakhweli abakaze baxelelwe ukuba iiholide zabo zinokushiya uphawu olumdaka kwiindawo abazindwendwelayo, utshilo uMarcie Keever. okhokele "iKhadi leNgxelo yokuSingqongileyo yeSinqanawe seCruise."
I-Cruise Lines International Association, iqela elimele iindlela zokuhamba ngenqanawa ezingama-24, yayigxeka le ngxelo, iyibiza ngokuba ayinamkhethe, ineziphene kwaye ingahoywa “isibakala sokuba iindlela zethu zokuhamba ngenqanawa ziyayithobela kwaye kwiimeko ezininzi zodlula yonke imimiselo yendalo esingqongileyo.”
"Kulusizi ukuba aBahlobo boMhlaba babhale ulwazi olungelulo xa eneneni eli shishini lenze inkqubela phambili enkulu kwiminyaka eliqela edlulileyo ekuqhubeleni phambili itekhnoloji kunye nokuphuhlisa iinkqubo ezihamba kude ekukhuseleni okusingqongileyo," utshilo umbutho kwingxelo.
Abahlobo boMhlaba balinganise imigca yokuhamba ngenqanawa kwiindidi ezintathu: ukucocwa kwamanzi amdaka, ukuncitshiswa kongcoliseko lomoya kunye nokuthotyelwa komgangatho wamanzi kumanzi aseAlaska. Ikwakhuphe ibakala elilula lokupasa/lokusilela ukufikelela kumgca ngamnye kulwazi lokusingqongileyo.
Eli qela lathi iFlorida, eneminye yemithetho engqongqo ethintela ukungcoliseka kweenqanawa zokuhamba ngenqanawa, ikwanamazibuko amathathu aphezulu okuhamba ngeenqanawa: iMiami, iPort Canaveral kunye neFort Lauderdale.
IAlaska kunye neCalifornia bathathe esona sigqibo siqinileyo kwilizwe lonke ngokuchasene nongcoliseko lwenqanawa yokuhamba ngenqanawa, lathi iqela.
U-Keever uthe ezinye zeendlela zokuhamba ngenqanawa bezisebenza ukwenza iinqanawa zayo zingangcoliseki, ngakumbi kwindawo yokucoca ilindle. IHolland America, iNorwegian, Cunard kunye noCelebrity bafumana amanqaku aphezulu ngokucocwa kogutyulo oluphezulu kwiinqanawa zabo.
I-Carnival kunye ne-Disney bafumana "ii-Fs" zokucoca ugutyulo.
I-Disney, eneenqanawa ezimbini kunye nezimbini ezisakhiwayo, zinokufumana amanqaku angcono kunyango lwamanzi amdaka kulo nyaka uzayo kuba ithembise ukwenza uphuculo kuzo zonke iinqanawa zayo, utshilo uKeever. Inkampani ibhengeze kwiveki ephelileyo ukuba okokuqala izakuqala ukubonelela ngokhenketho eAlaska ukusukela ngo-2010.
UKeever uthe itekhnoloji isendaweni yeenkampani zeenqanawa zokuhamba ngenqanawa ukuhlangabezana nemithetho engqongqo yokusingqongileyo yaseAlaska - ibango elaphikiswa ngumongameli weAlaska Cruise Association uJohn Binkley. Uthe iindlela zokuhamba ngenqanawa ziya kuvuya ukufumana itekhnoloji entsha efikelelekayo ukuhlangabezana nemigangatho engqongqo yeAlaska ukuba ibikhona, kodwa akukho nto inokuthenjwa.
Binkley akafumanekanga ukuba enze izimvo ngoLwesithathu.
Kwi-2008, i-12 yeenqanawa ze-20 ezivunyelwe ukukhupha emanzini ase-Alaska zifumene ukuphulwa, ikakhulukazi i-ammonia kunye neentsimbi ezinzima, uKeever uthe. Inyani yokuba iinqanawa ezisibhozo azizange ziphule umthetho zibonisa ukuba inokwenziwa, utshilo.
Iindlela ezili-10 zokuhamba ngenqanawa zifumene amabanga asezantsi okunciphisa ungcoliseko lomoya. Abasixhenxe kwabalishumi kwiindlela zokuhamba ngenqanawa bafumana ii-“Fs.” NguNkosazana kuphela owafumana ibanga eliphezulu.
UPrincess uchithe izigidi ukunciphisa ukukhutshwa kweenqanawa zokuhamba ngenqanawa, utshilo uKeever.
Inkampani ityale i-4.7 yezigidi zeedola kwizibuko laseJuniau ukuze iinqanawa ezibophe apho zikwazi ukungena kumandla aselunxwemeni endaweni yokusebenzisa iinjini zazo ukunika amandla kubakhweli kunye nabasebenzi. Inkampani ikwatyale imali eyi-1.7 yezigidi zeedola ukuphucula izibuko laseSeattle. U-Keever uthe iinqanawa ezisithoba zePrincess' 17 zixhotyiswe ngeeplagi zombane.
Izibuko laseLos Angeles kamva kulo nyaka kulindeleke ukuba libe namandla aselunxwemeni kwindawo yalo yokukhwela iinqanawa, utshilo.
Ngaphandle kokuphuculwa kwamandla kumachweba kunye nokuhlaziywa kweenqanawa, iinqanawa zokuhamba ngeenqanawa zinyanzeliswa ukuba zitshise i-bunker fuel ngelixa i-port, "i-fuel-burning" i-fuel e-1,000 ukuya kwi-2,000 ngamaxesha amdaka ngaphezu kwe-diesel iloli ye-diesel, u-Keever uthe.
Iinqanawa zokuhamba ngeenqanawa nazo zinokuxhotyiswa ukutshisa idistillate yaselwandle, isibaso esicocekileyo esitshisayo kune-bunker fuel, utshilo uKeever. ICalifornia isandula kufuna zonke iinqanawa ezihamba elwandle, kubandakanya iinqanawa zokuhamba ngenqanawa, ukuba zitshise amafutha acocekileyo ngaphakathi kweemayile ezingama-24 elunxwemeni.
